This product, known as Argus Open Numerical...
US GeoData digital elevation models
Water Resources Division, U.S. Geological Survey
1997, Fact Sheet 102-96
Digital elevation model (DEM) data consist of a sampled array of regularly spaced elevation values referenced horizontally either to a Universal Transverse Mercator (UTM) projection or to a geographic coordinate system. The grid cells are spaced at regular intervals along south to north profiles that are ordered from west to...
The Universal Transverse Mercator (UTM) grid
Water Resources Division, U.S. Geological Survey
1997, Fact Sheet 142-97
The most convenient way to identify points on the curved surface of the Earth is with a system of reference lines called parallels of latitude and meridians of longitude. On some maps the meridians and parallels appear as straight lines. On most modern maps, however, the meridians and parallels may...

The Late Triassic bivalve Monotis in accreted terranes of Alaska
Norman J. Silberling, J. A. Grant-Mackie, K. M. Nichols
1997, Bulletin 2151
Late Triassic bivalves of the genus Monotis occur in at least 16 of the lithotectonic terranes and subterranes that together comprise nearly all of Alaska, and they also occur in the Upper Yukon region of Alaska where Triassic strata are regarded as representing non-accretionary North America. On the basis...

Simulation of ground-water flow in the Coastal Plain aquifer system of North Carolina
G.I. Giese, J. L. Eimers, R. W. Coble
1997, Professional Paper 1404-M
A three-dimensional finite-difference digital model was used to simulate ground-water flow in the 25,000-square-mile aquifer system of the North Carolina Coastal Plain. The model was developed from a hydrogeologic framework that is based on an alternating sequence of 10 aquifers and 9 confining units, which make up a seaward-thickening wedge...

1997, Journal of Coastal Research (Special Issue 25) 49-62
Detailed velocity distributions within the benthic turbulent boundary layer were measured by a Broad Band Acoustic Doppler Current Profiler (BB-ADCP) in South San Francisco Bay, California. In "mode 5", the BB-ADCP was able to measure velocity in 5 cm increments. The validation of these measurements was achieved by comparing the...
Assessment of saltwater intrusion in southern coastal Broward County, Florida
M. L. Merritt
1996, Water-Resources Investigations Report 96-4221
Of the counties in southeastern Florida, Broward County has experienced some of the most severe effects of saltwater intrusion into the surficial Biscayne aquifer because, before 1950, most public water-supply well fields in the county were constructed near the principal early population centers located less than 5 miles from the...

1996, Conference Paper, Proceedings: International Wildland Fire Foam Symposium and Workshop
Fire retardants and suppressants used extensively in North America are often applied in environmentally sensitive areas that may contain endangered, threatened, or economically important plant and animal species. We conducted laboratory acute toxicity tests in both hard and soft waters with five commonly used fire control chemicals (Fire Trol LCG-R,...
